[Galaxy Tab 7.7 General] dun1982:
Thx for help. I'm setting now Ubuntu 12.04 LTS on my spare laptop (Acer TimelineX 3820TG) with needed build environments.

I have no guarantees that anything what I'm trying will work, but I really hope that I can avoid bricking my gt-6800 and get the cm10.1 kernel to work with the device. After that it should be quite straight forward to get the build up and running in some shape.
[Galaxy Tab 7.7 General] dun1982:
Ok, now I have the environment set-up, but there are no kernel confs available. So it seems that I have to either found them somewhere or create a new one and then try to figure it out. It seems that Iocerras kernel is a bit old (3.0.xx series). We'll, as soon as I have something to show, I'll put the information available in the development section on this forum and release the first version of the platform. But currently the image build is on hold because I need to concentrate my daily work.
[Galaxy Tab 7.7 General] xrayA4T:
Will the cm10.1 not work?
[Galaxy Tab 7.7 General] dun1982:
There is no build for gt-p6800 available in CM10.1 with kernel sources. I'm still investigating where I might find the needed sources so that I can compile the kernel and start upgrading it towards 3.5.xx release.

Works great :)
[Galaxy Tab 7.7 General] dun1982:
Heh, anyway I think I'm getting quite close to on finishing the first ever build for ubuntu-touch for gt-p6800...

I had to create two new repositories because the kernel and device configuration that is available is so messed up. I hope I do not have many legacy kernel problems anymore when I'm making the first build here.

Are there any gt-p6800 dev's around still or has the ship sailed already from this device. I really like it because its premium build quality, but I hate it if there is no one else interested on the device anymore :)
[Galaxy Tab 7.7 General] dun1982:
YEAH, first build done.

If someone has a good idea where to dump the image for others to test, please notify me in this thread or PM me.

[Galaxy Tab 7.7 General] xrayA4T:
I use Ubuntu as my desktop OS at home. Canonical is looking to make your Ubuntu phone your only device. Android is a great mobile platform but is not a desktop platform. Ubuntu has a desktop platform and a tv platform both sitting on top of a common Linux kernel. If Ubuntu phone works as promised you'll have all three platforms in a single unified device depending on what the device is connected to. Standalone it is a phone/phablet/tablet depending on the device. Attach it to a tv and it is a media centre. Dock it to a keyboard, mouse and monitor it becomes a full desktop. Each with their own interface optimised for that use case rather than trying to make one interface that sort of works for all. If Canonical pulls this off it will be a winner.

I would definetely prefer a well running Ubuntu to Android. Meaning phone, data, wifi working. The hardware of my tablet is almost as good as the hardware of my laptop running Ubuntu. 1.4Ghz vs 1.8 Ghz, 1Gb Ram vs 2.5Gb, powervr xyz vs geforce 7400m. One device to rule them all ;).
[Galaxy Tab 7.7 General] dun1982:
Yup, me too, but too bad i do not have that much time or interest to go back and look for the problems before Easter. What would be helpful is if someone developer minded find a way to get the kernel to a shape that has working network drivers and screen. As far as I ended up, is that if I insmod the ath6kl.so, it will reboot the whole device.

So there is lot to do in the kernel level. The interesting part is that we cannot use the Iocerra's CM-10.1 kernel setup nor build (or it does not work at all). I have tried that as well, but for no avail. I can however build the CM10.1 from the soruces no isseues...

I'm a noob on the Dev level. I know android and am pretty proficient in certain areas. But would it be theoretically possible to change kernels from within the os. Basically through an app, not in recovery on the boot loader level kind of like swapping boot images on certain older phones. Correct me if I'm wrong or if its not even possible. I know its not a big deal to boot to recovery to change kernels, it would just be a step for development or my large coffee brain possibly over thinking.

It takes a few days to tell the true performance of a kernel, I believe. So if you flash a different one every morning, in theory, you wouldn't be able to see the true benefit of the custom kernel. Sorry if I'm wrong on this subject. But that app works amazing if that's what you're looking for.

I take it back, its not literally everyday. More like two. Technically you should be able to see the difference in responsiveness right away. Between franco and trinity there is definitely a better feel to trinity in my opinion. Yes as far as battery performance goes, the kernel needs a couple charge cycles to settle in, this I know. I haven't tried faux yet and matr1x does very well with battery life. I'm really liking the latest iteration of trinity tf105 and I will stay right where I am for a few more days.

[HTC One X] Xmister:
Hi guys!

I think the need of repacking and repacked images for every kernel-rom combination is a huge nuisance.

What would be if ROMs would contain their ramdisk on the system partition, and the kernels would just contain a minimal ramdisk that loads the ROMs ramdisk?

One idea:

My first idea would break compatibility with system recovery zips, so a little modified:

There would be a new "ramdisk" directory on system partition, that would containt all the ramdisk files a ROM should have, except the system folder.

So it would contain:

bin

etc

data

...

init.rc

...

and so on.

The init in the actual ramdisk would mount system first, and then make the links:

/bin -> /system/ramdisk/bin

/etc -> /system/ramdisk/etc

/data -> /system/ramdisk/data

...

and then we would include init.rc from /system/ramdisk.

Of course all the ROMs would need to change, but after that, there would be no need for repack. Also for the old ROMs, factory ROM, some could still repack.
[HTC One X] Freezeil:
That's a nice idea! I thought a little bit about it and here are my thoughts (a novice, please don't laugh at me :silly:):

if I understand your idea correctly, your intention is to store the specific ROM's ramdisk in the rootfs, and make a global, generic ramdisk which will be stored in all the kernels.

Upon loading the kernel's ramdisk, it will know to take the ROM's ramdisk from the rootfs (upon mounting it?) and run whatever is in it, thus eliminating the need for repacking.

Do correct me if I'm talking absolute rubbish, but wouldn't this be a security risk?

Currently with S-ON, you actually can't change the kernel's ramdisk, but if the ramdisk will be stored in a writeable filesystem...?
[HTC One X] Xmister:
On s-off phones ramdisk can be changed on the fly with repacking, and reflashing the kernel if rooted. There is no more security risk in this, than that. And system is ro mostly, so file corruption isn't something to be afraid of either.
[HTC One X] Freezeil:
I agree, other than the fact that repacking+reflashing the kernel on S-ON devices can only be done manually, by a person (which is the device owner, most of the time), and most of the One X's out there are S-ON and not S-OFF...

Sure, a malicious coder can write evil code in the kernel, but that's relatively less threatening since most kernels have their sources published.

If the ramdisk will be placed on a rw fs (or a ro, but it matters not because of the user elevation rooted users can achieve easily), we are adding the risk of malicious code accessing and changing that ramdisk, without the user's knowledge.

Still, this seems like a nice programming challenge, so I'm up for the task. Will start reading the init's code and see how to do it :)

Guys i would like this thread kept with minimal off topic please, i have already deleted three posts here...

[HTC One X] TripNRaVeR:
Is anyone really seriously responding to this?

What would be the advantages of modifying Android layout for 1 device only, its so annoying to see this stuff here when even a s-off thread is locked.. currently when all the sources are going to a way whereas all the basic files are device independent makin this even more.. timewasting effort and still we have the same issues. You just lock every rom dev to a ramdisk instead of a kernel dev to a ramdisk.

This is only usefull with a locked bootloader. I never implement this, another reason is that i spend more time getting my stuff aligned with the mainline that is giving me more succes then randomly adding stuff the a system partition.

Oh and btw when youre system partition gets messed up or altered or whatever you wish you had a decent ramdisk. Not to forget the huge amount of users ending up like that and flooding the forums with questions.
[HTC One X] Xmister:
Adding 1 directory is not an "android layout modification". They are moving there, yet it isn't independent between the ROMS even on the same phone.

That's what 99% of us have.

If your system messes up you are probably can't boot android either. What the r=1 user do this time? Goes to recovery, wipe, if that doesn't help, reflash.

Since we have different kernel and ramdisk for recovery, this is not a problem.
[HTC One X] TripNRaVeR:
Lol 99% of us DOESNT have this, if we did we cant flash custom roms.

Adding 1 directory is changing Android layout, Google doesnt have it, you want it on /system you alter the layout. Plain simple.

Also if anyone, like me, doesnt like to include youre mod users still need to repack between roms who contain that dir and roms who dont have that dir. That repacking also requires the same kernel edits so basicly you just move the repacking arround.
[HTC One X] Xmister:
Sorry, I was reading S-ON in my mind, I don't know why.

But then it's not only useful for locked devices. It helps just in what it says in the title.

Yes, it can only work if there are enough ROMs taking the change.

And right, call it a layout modification. Why is adding 1 directory bad for anything? It won't break compatibility over anything.
[HTC One X] TripNRaVeR:
I dont want to call it bad, i just dont think this developer discussion, as we all know, and probably you also, this kinda stuff is only stuff to think about. As long as the whole community isnt adopting this it will never happen.

As you also state, it only works when enough roms are using it.. THAT is my problem here, currently we need to repack because of compat. issues sometimes.

Cool that sucks i know, you come up with this idea, without proper thinking people say cool lets do that.

When building roms, some devs like this and some devs dont like this, that will happen you can count on that. If you have 3 devs that dont use it you could end up doing MORE repacking then we need to do now.. that is what i'm trying to explain..

Therefore i said cant believe this is seriously looked into at a high mod level dev section. Hope i made my point clearer now
[HTC One X] Xmister:
So your point is: "They won't use it anyway"

And why would need more repack? If half of the ROMs would use it, there would be half as much repack needed.

And in the section rules it says even overriding a notification widget should go in this forum. It's not S-OFF forum, it's Dev related forum, such as my idea.
[HTC One X] Giblet-dono:
Lets all be honest and say: people (users) are lazy...

So if they CAN, they WILL go for the non-repack option

Now, as I am a normal User I am not sure what the exact mechanics are behind this.

But as far as I understand it would be less work for the kernel devs.

They only have to take the "minimal" ramdisk, and put it in their kernel.

The rom makers will have to do "more" work.

But it is work they already are doing, most roms are released with a specific boot.img/kernel.

Some romdevs already are making their own kernels to get some functions (within the ramdisk) to work!

They will gladly adapt to a new way of using ramdisks...

Now I suggest to X Mister, Go for it!

Make a tutorial for rom devs, make a tutorial for kernel devs, and make a tutorial for users.

Make it easy for everyone to use this method!

Now I get what Trip is saying, when we have S-Off we won't need this..

This is very true, but S-Off is most likely not going to happen any time soon.

So in the mean time, why not try it for this device?

Letting my phone do whatever it wants when I'm on wifi and my phone is sitting idle, my phone uses around 1%/hour of battery life.

[Verizon Samsung Galaxy S III] AtariDroid:
This is an app written and distributed by a component manufacturer. They will cut speed/processing power as much as they can to make the device use less battery. This inherently means the app will take control of the CPU/governor adjustments. A kernel such as KT with an app that LOCKS frequencies may prevent this, but also will render the app useless.

They aren't concerned with the same things as we in the rooting world are. We want to push as much processing power as possible while using the least amount of electrical power needed, not slow the device down while hoping ppl don't notice. Lol..

I have a question, that I've had trouble finding the answer to.

Is there a need to flash a new radio to my phone? Are there benefits to flashing a new one?

I currently use my N4 with Straight Talk (AT&T).

Thanks.
[Nexus 4 Q&A, Help & Troubleshooting] halluci293:
Depends. If you are updating your rom to 4.2.2, it's probably a good idea to flash the corresponding radio as well. If you are on 4.2.1, there are reports of incompatibility with 4.2.2 radio, so don't update. Otherwise, different radios may give you better signal/connection speeds, but it's hard to say.

Also, 4.2.2 radio disables lte, but since you're on straight talk it doesn't matter.
[Nexus 4 Q&A, Help & Troubleshooting] wvcadle:
Do the ROMs not flash the appropriate radio for the android version? I updated to 4.2.2 before flashing MoDaCo, so do I have the correct radio?
[Nexus 4 Q&A, Help & Troubleshooting] halluci293:
No, ROMs generally contain only the kernel and system images. Updated bootloader and basebands need to be flashed separately.

Edit: The above applies to custom ROMS. If you flashed stock 4.2.2, you may have the updated radio. You can check by going into settings->about phone->baseband version. For 4.2.2, the number should end in 48, 4.2.1 ends in 33.
[Nexus 4 Q&A, Help & Troubleshooting] wvcadle:
Great. So I do have the correct one for 4.2.2. Are there different versions for the same ROMs, or do we only need to make sure we have the correct radio for the version of android we have?
[Nexus 4 Q&A, Help & Troubleshooting] halluci293:
Radio and bootloader version are generally linked with your Android version. AFAIK, no one makes custom radios/bootloaders, so they're always stock.
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
No one make custom radios/bootloaders because they're closed source. Its impossible to make a custom radio/bootloader unless you are LG/Google (and its respective manufacturers for that phone).
